DrTim’s Aquatics Ammonium Chloride Solution – 8 oz – Fishless Cycling Formula for Freshwater & Saltwater Aquariums – Treats 400 Gallons

DrTim’s Aquatics Ammonium Chloride Solution has been a game-changer in setting up my new aquarium. This reagent-grade solution simplifies the fishless cycling process by providing a precise ammonia source, eliminating the need for guesswork. When used in conjunction with DrTim’s One & Only Live Nitrifying Bacteria, I was able to establish a healthy biofilter in my tank without subjecting any fish to harmful ammonia or nitrite spikes. The easy-to-dose liquid formula treats up to 400 gallons, making it both efficient and cost-effective. I highly recommend this product to both novice and experienced aquarists aiming for a safe and effective aquarium setup

Got the job done. 1 ppm was just fine for me though the 2 ppm would have been a lot.

Ordered this to help me jumpstart the cycle on my new Reef tank. Worked great! Tank was cycled in about 14 days. Great value and better than fish-in cycling.

This stuff helped cycle my tank pretty quick. I was using it with Seachem Stability and saw nitrites show up in just a couple days, which was way faster than I expected. It’s a clean ammonia source and didn’t cloud the water or mess with the pH. Only issue I had was with the dosing—it says 4 drops per gallon but the cap has different markings and it’s not super clear how much to use if you need to redose. I ended up just testing a lot and going by that. Still, it did exactly what I needed it to do and I’d use it again, just wish the instructions were laid out better.

Dr Tims ammonia is Excellent for setting up your fishless aquarium. Easy to follow directions.

I read to use my fish food to create ammonia for my cycle, COMPLETE LIE. I'd have needed to use 15 cans of it to produce the affect needed to cycle my fish tank. With 4 drops per gallon of this you can quickly produce the ammonia needed to start your cycle. It took 7 days and I had Nitrates and Nitrates and a LOT of them. My tank finished cycling right on schedule thanks to this product. I would have been monumentally screwed otherwise and if you're new to this please heed my words and use this to cycle your tank (FISHLESSLY OF COURSE) because it will save you time, frustration, and lack of understanding what's going wrong.Set up your tank. Use this. Get the right readings for Nitrates. Add your fish.That simple. I now know how to cycle a tank thanks to Dr. Tim. Enjoy this picture of my healthy thriving tank.

Like a few other reviews, I have tested the water after adding this product 3 different times and still 0 ammonia. I even added the product directly to a tube and tested it, still nothing. Snake oil product, do not buy

used this to get a good bacteria cycle for my axolotl tank. it worked perfectly
